Remote command:
CALCulate<n>:MARKer<m>:COUNt:FREQuency?
Noise Meas On/Off
Switches the noise measurement for the active marker on or off. The corresponding
marker becomes the normal marker.
For more information on noise measurement see
"Measurement of Noise Density"
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:NOISe[:STATe]
CALCulate<n>:MARKer<m>:FUNCtion:NOISe:RESult
Phase Noise
This softkey opens a submenu that contains functionality to configure and perform
phase noise measurements.
Phase Noise On/Off ← Phase Noise
Switches the phase noise measurement with all active delta markers on and off. The
correction values for the bandwidth and the log amplifier are taken into account in the
measurement.
Marker 1 is activated, if necessary, and a peak search is performed. If marker 1 is acti-
vated, its position becomes the reference point for the measurement.
Deltamarker 2 is activated and can be used to read out the phase noise value at a
given frequency offset.
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:PNOise[:STATe]
CALCulate<n>:DELTamarker<m>:FUNCtion:PNOise:RESult?
Ref Point Level ← Phase Noise
Opens an edit dialog box to enter a reference level value. All relative level values of the
delta markers refer to this reference level.
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:FIXed:RPOint:Y
Ref Point Frequency (span > 0)/Ref Point Time (zero span) ← Phase Noise
Opens an edit dialog box to enter a frequency reference or time value. All relative fre-
quency or time values of the delta markers refer to this frequency reference. For phase
noise measurement, input of reference time is not possible.
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:FIXed:RPOint:X
Peak Search ← Phase Noise
Sets the maximum value of the selected trace as the reference point.
Remote command:
CALCulate<n>:DELTamarker<m>:FUNCtion:FIXed:RPOint:MAXimum[:PEAK]
